Growth and peostive wear properties of mpcvd diamond coatings on sintered tungsten carbide substrates

摘要

Adherent diamond coatings up to approx 35 #mu# m thick have been grown by microwave plasma CVD (MPCVD) on sintered tungasten carbide (WC) substrates and their erosive wear properties investigated under high velocity air-sand erosion testing. Two different sintered tungasten carbide (WC) substrates have been investigated and compared, the binder being either 6
